Atomic multi-operation batching with one passkey approval

[Miracle656]

Background

Today each action is a separate tx + passkey prompt. Composing several operations (approve + swap, or multi-send) into one signed transaction improves UX and atomicity.

What to build

A batch() API that collects multiple Soroban invocations into a single transaction, builds one auth payload, and gathers a single passkey assertion covering all auth contexts.

Key files

• sdk/src/useInvisibleWallet.ts
• contracts/invisible_wallet/src/lib.rs (verify multi-context __check_auth)

Acceptance criteria

• Multiple ops succeed/fail atomically
• One passkey assertion authorizes all contexts
• Test: partial-failure rolls back the whole batch

I’d like to work on this issue because it contributes to improving the project's functionality, reliability, and overall user experience. I enjoy contributing to open-source projects and collaborating with maintainers to deliver clean, maintainable, and well-tested solutions.

I have experience working across frontend, backend, testing, API integration, debugging, and performance optimization tasks. I'm comfortable analyzing existing codebases, understanding requirements, implementing features or fixes, writing tests, and ensuring changes align with project standards and acceptance criteria.

My approach is to first understand the current implementation, identify the most maintainable solution, implement the required changes, add or update tests where necessary, and verify that everything works correctly before submitting a PR. I can communicate progress clearly and incorporate feedback quickly throughout the review process.
